Application March 16, 1953, Serial No. 342,659

1 Claim. (Cl. 41--1) This invention relates to methods of and machines for applying leaf edges to books. The application of leaf edges to religious and other works, pursuant to the method below, the method of this invention is set forth in connection with a typical machine which may be used in carrying it out.

As will appear from a consideration of the drawings and description, the method may be carried out in machines of other forms; such variations in the` machine as well as in the method, within the scope ofthe appended claim, shall be deemed to be within the purview and comprehension of this invention, and covered by this application.

In the drawings:

Fig. 1 is a top plan schematic view of a machine embodying the invention,

Fig. 2 is an enlarged, fragmentary elevational view thereof, taken on line 2 2 of Fig. l,

Fig. 3 is a perspective view of one form of such machine, and

Fig. 4 is a perspective view of a form of wedge device which may be used in connection therewith.

As shown in the drawings, the machine of my invention comprises a stop bar to which a pair of rail rods 11, 12 are connected in parallel spaced relation, as shown in Fig. 1. A bearing plate 13 is movably disposed on said rods, as, for example, by being provided with openings 14, 15, freely receiving said rods. The stop bar 10, rail rods 11, 12, and bearing plate 13, define an opening 16 therebetween for the reception of bank of books 17 which are to have leaf applied to an edge thereof. The leaf is preferably applied tothe edge of the Vbooks initially in any suitable manner, as, for example,

by manually positioning the leaf on said edges. In the normal procedure followed to that end, a single sheet of gold leaf would cover the edges of a plurality of books in length, and such sheets would be applied in overlapping relation. The bank of books 17 positioned in the opening 16 will have had applied to the edge thereof to be treated, the sheets of gold leaf (or other leaf sheets). The bank of books is rmly secured in the opening 16 pursuant to the present invention, and a burnishing tool 20 (Fig. 3) is reciprocated on said bank of books to burnish said leaf into the edges of the book. Pursuant to the present invention, the book edges to be treated are held in firm, tight relation for the burnishing step. Toward that end, preferably there are interposed one or more wedge members 21 (Fig. 4) disposed in downwardly tapered position between the bearing face 18 (Fig. l) of the plate 13 and the stop bar 10 and in contact with said bank of books. If desired, more than one wedge member may be so inserted, as shown, for example, in connection with the bank 17 of books in Fig. 3. Other banks of books, as, for example, shown at `2,724,201 ilatented Nov. 22.,`

22, 23, in Fig. 3 may be similarly disposed `intermediate the stop bar 10 and bearing plate 13, pursuantto the invention, sothat, for example, several banks of books may be positioned for burnishing at one setting pursuant to this invention. The burnishing tool 20 may be manipu-v lated by the workman along the edge of the book, to burnish the leaf thereinto; then, upon moving the bearing plate 13 away` from the stop bar 10, the banks of books may be removed. In the convenient form of the invention shown in Fig. 3, the stop bar 10 is shown mounted on a frame indicated at 24, and the stop bar is provided with openings 25, 26 (Fig. 1) through which the rail rods 11, 12 pass. The forward ends of the rail rods are secured to the forward end 25 of the frame, as, for example, by passing said forward ends of the rail rods through an extended housing 27 rigidly secured to the forward end of the frame. Anchoring means 28 maybe used to secure the forward ends of the rail rods to said housing 27. The movably disposed bearing plate 13 may be actuated by hydraulic means generally indicated at 29, 30, having hydraulic conduits 31, 32 connecting the hydraulic means 29, 30 to hydraulic cylinders 33, 34 (Fig. 2) in which pistons 3S, 36 are reciprocated, responsive to hydraulic pressure on actuation of the hydraulic means 29, 30. The means for actuating the latter may be of any desired or convenient type, as, for example, the levers 37, 38, which may be manually operated so as to pump the hydraulic iluid and thereby move the plate 13 toward the stop bar 10 to effect compression of the banks of books betweenthe members 10, 13. In the compression action above noted, wedge members 21 preferably cooperate so that the upper edges of banks of books which are to be burnished are compressed most tightly intermediate said members 10, 13.

The method and machine of this invention have been found in practice to be highly ellicient in operation and to enable the rapid and economical processing of banks of books for application thereto of burnished leaf edges, in a highly uniform and satisfactory manner. The hydraulic means may be provided with accessory devices such as, for example, the pressure gauges 39, 40. The cylinders 33, 34 may be secured directly to the housing 27 or may be locked as at 41, 42 to casings 43, 44 on the housing 27, as shown in Fig. 2. The rearward ends of the rail rods 11, 12, which pass through the stop bar 10, may be threaded as shown at 45, 46, so that, by taking up on the nuts 47, 48, the distance between the bearing plate 13 and stop bar 10 may be varied independently of hydraulic means 29, 30. The term hydraulic as herein used is defined to mean any controllable pressure-exerting medium.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A machine for a plurality of parallel clamping banks of books with their edges exposed in a plane for the burnishing of leaf applied thereto; comprising a frame, an elongated horizontally disposed housing secured to one end of the frame, an elongated stop bar` supported in the opposite end of the frame in spaced parallel relation to the said housing, a pair of laterally spaced parallel rods disposed at right angles to said housing and said stop bar, corresponding ends of said rods being secured to said housing, said stop bar being provided with a pair of apertures through which the opposite ends of said rods loosely extend, said opposite ends being; threaded, nuts on said threaded ends engaged with said stop bar and being adjustable for varying the spacing between said housing and said stop bar, an elongated bearing plate disposed between said housing and said stop bar in parallel relation therewith and being provided with a pair of apertures loosely receiving said rods, said stop bar, rods and bearing plate providing a rectangular Y 3 space which a plurality of parallel banks of'books ai?, adapted t0 be, pnsitoned, fQr simultaneous clamping action thereon through said stop bar and said bearing plate, a pair of spaced hydraulic cylinders supported Within; Saidhojusing anddisposed-between same; and said bearing plate, pistons cooperating. with said cylinders and individually operatively engaged with said bearing plate, and a plurality of wedges fnaparatelyv insertable between the books;` inl :he individuali banks for equalizingy the pressure n all the banks while being simultaneously clampedv in operative position.
